Die Stone, Stone & Plaster
As one of the market leader for dental stones and plasters, SHERA lay great emphasis on the quality while developing and producing. All SHERA stones and plasters are compatible with alginate, silicone, polyether as well as hydrocolloid impressions and offer excellent technical advantages such as:
~ Very fine grained consistency
~ Excellent flow characteristics
~ Good thixotrope quality
~ Firm margins even around thin preparations
~ Easy processing: sawing, grinding, trimming without splintering
~ Precise reproduction of details
~ Smooth, dense surfaces
~ Consistent technical data
The SHERA product range includes perfect stones and plasters for any application: from working to presentation models, or from CAD/CAM to opposing models.
